Abstract: Embodiments of this disclosure include a channel access method in a wireless local area network (WLAN) and related apparatus. In the method, a communication device receives a first overlapping basic service set (OBSS) frame on a primary channel, determines a first channel with a busy channel state based on bandwidth information carried in the first OBSS frame, and performs channel contention when switching from the primary channel to a second channel. After the communication device backs off to 0 on the second channel, the communication device determines a third channel used for transmitting data, where the third channel does not include any sub-channel of the first channel, and the first channel includes the primary channel.

Abstract: Embodiments of this application provides a multi-link synchronous transmission method and apparatus. The method includes: The transmit MLD sends a first transmission frame to the receive MLD at a first moment on the first link when a first condition is met. The first moment is determined based on a second moment and/or a third moment, the second moment is a moment at which a backoff counter of the first link decreases to 0, and the third moment is a sending moment of a second transmission frame on the second link. The first condition includes: (1) The backoff counter of the first link is 0, and (2) the second transmission frame is located in a transmission opportunity TXOP on the second link.

Abstract: First information received by a first MLD on a first link is used to determine whether a BSS configuration of a second link is updated. In response to the BSS configuration of the second link not being updated, the first MLD directly transmits a data frame on the switched-to second link or the second link whose status is transited, and the data frame is not transmitted until a beacon frame is received and a latest parameter of the BSS configuration is obtained on the switched-to second link or the second link whose status is transited. A waiting time occurring before the data frame is transmitted is reduced.

Abstract: A method for coordinated communication and an apparatus for coordinated communication are provided. The method includes: a first access point (AP) sends an announcement message and/or a polling message to one or more second APs. The announcement message announces that the first AP may share a time resource of the first AP. The announcement message may further include identifier information that indicates the one or more second APs, and time information that indicate communication or channel contention of the one or more second APs in the time resource shared by the first AP. The polling message may be used to notify a second AP to start to use, at a preset time, a channel resource shared by the first AP with the second AP for communication or start channel contention at the preset time.

Abstract: This application provides a communication method and an apparatus, and relates to the field of communications technologies, to reduce a phenomenon that an acknowledge rule is violated in some scenarios. The method includes: After a receive device receives a first data unit from a transmit device through a first link, the receive device sends receiving status information of the first data unit to the transmit device through the first link, unless the first data unit meets any one of a first preset condition. The first preset condition includes: Correctly received information of the first data unit is fed back through another link, or an acknowledge policy corresponding to the first data unit is no acknowledge. The communication method in embodiments of this application is applied to a multi-link data transmission process.
